A graph-based technique to manage quality through the product lifecycle

In this paper a technique to orchestrate a whole software product is presented. This technique uses a directed graph as mechanism to connect all the artifacts that integrate the product. The artifacts are represented as nodes and the relationships between them are represented as arcs. In the graph, any type of artifacts from the different development phases can be represented. Quality can be managed at two levels: (1) Artifacts content, (2) Correspondence between the artifacts. A set of guidelines are defined to manage the quality at the level of correspondence. Scenarios for the use of this technique are stated in order to continue with this approach definition. This technique differs from other approaches because it integrates all the development phases while other techniques consider only artifacts from one or two phases.
